CIFDP: WMO Coastal Inundation Forecasting Demonstration Project



Coastal inundations are an increasing threat to the lives and livelihoods of people, living in low-lying, highly populated coastal areas. The management of such risk represents a great challenge to scientists and policy-makers in the areas of meteorology, hydrology, oceanography, emergency management and coastal planning. 

With a view to improving safety-related services for the community, as a fundamental priority of the WMO, the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM ) and the WMO Commission for Hydrology (CHy) have initiated this Project in order to meet the challenges of coastal communities’ safety and socio-economic sustainability through the development of coastal inundation forecasting and warning systems at the regional scale.

Upon completion of Sub-Projects of CIFDP, countries will implement an operational system for integrated coastal inundation forecasting and warning, providing objective basis for coastal disaster (flooding) management; contributing to saving lives, reducing loss of livelihood and property, and enhancing resilience and sustainability in coastal communities. Each Phase of the Project will provide implementing countries with valuable input and experience, regarding the assessment and awareness of the issues of coastal inundation management within its governments. It will also assist the countries to advance steps toward the integrated forecasting warning services.

Countries that intend to develop a sub-project are invited to prepare and deliver to WMO an Initial National Agreement between participating national agencies responsible for coastal inundation forecasting and warning, to be the basis of a Definitive National Agreement (DNA).

Casualties by Cyclones and Storm Surges


Deaths in tropical cyclones in each year, for highest ranks in the history (with indication of relative level of casualties by major tsunami events). Most of fatalities in tropical storms are due to storm surges. All casualty figures are estimates very widely according to sources. (Dube, 2007)
